FLIGHT, NOVEMBER 24, 1932 TAILLESS : The Nicuport-Delage 941 light plane has a 3-wheel undercarriage, the single front wheel being steerable. construction which permits of obtaining a perfect stream line form without panel beating, the system, briefly ex plained, consisting in giving all the panels a trapezoidal shape. In this way the angles merely vary in accordance with the amount of taper, but all edges are straight, and no beating is required to make them follow the desired contour. The internal framework to which the panels are attached is in the form of extruded T-sections. Latecoere.—The single machine exhibited is a type Lat.29, which is a strut-braced monoplane, and a twin- float seaplane. The machine obviously is a military version of the Lat.28 postal machines used by the Aeropostale com pany. A huge wing, said to be for a transatlantic sea plane, is also exhibited, standing on end, with its tip nearly reaching the roof of the Grand Palais. Levasseur.—Pierre Levasseur shows a torpedoplane of somewhat unusual design. The arrangement of the wings may, perhaps, be described as an inverted sesquiplane, as the main wing is a wire-braced monoplane structure, and the small top plane and its associated struts mainly serve to give a good angle to the anti-lift wires. The machine is known as the type P.L.151, and has a 650 h.p. Hispano 12 Nbr. engine. It carries a crew of three. The wing surfaces have large holes cut in the fabric to show the internal structure, which consists of built-up Duralumin box spars and Duralumin ribs. An interesting exhibit on this stand is a propeller carved out of " solid " steel. Further tests are being made, but M. Charles Frechet, the director of the firm, informs us that the preliminar ' tests have been very promising. Liore &• Olivier.—Size is the keynote of this stand, both the machines exhibited being well described as a Gros Porteur and a Tres Gros Porteur respectively. The former is the type LeO H.25, and is a twin-float seaplane fitted with two Hispano engines. The wing area is 120 m.2 (1,290 sq. ft.) and the gross weight S 400 kg. (18,500 lb.). The LeO 30 is a four-engined cantilever monoplane fitted with four Hispano engines, type 12 Nbr. At least these engines are to be fitted. At the show the nacelles were empty. A four-wheeled undercarriage is used, each of the wheels being independently mounted on its own tripod. The machine is a bomber with a wing area of 2,000 sq. ft. and a gross weight of 33,000 lb. The centre of attraction on the LeO stand is, however, the Pobjoy-engined Autogiro, a sketch of which was published in FLIGHT some weeks ago. The fuselage looks uncommonly short and " fat," but possibly is long enough. The directly-con trolled rotor is of the three-bladed type, and is tilted laterally by a wheel, while a to and fro move ment gives it its action as an elevator. The wheel arm runs en a curved rail, and a knurled knob locks it in any position. We gather that the machine has not yet been flown, not having been completed in time, but its future will be watched with interest. Morane-Saulnier.—True to their tradition, the Morane- Saulnier firm are concentrating exclusively on parasol monoplanes at the show, of which they exhibit a con siderable number. The 332 is stated to be designed for aerobatics and " grand sport." The engine is enclosed in a N.A.C.A. cowling. The type 315 is a preliminary training machine, while the 230 is intended for intermediate training and acrobatics. The last machine is the type 225, and is a single-seater fighter fitted with Gnome-Rhone 9 Kbrs. engine, N.A.C.A. ring, and " spats " over the wheels. The machine will begin to be delivered to squadrons early next year, and is believed to have a very good performance. Nieuport-Astra (S.G.A.).—Three Nieuport-Delage air craft are exhibited this year. One is a long-distance reconnaissance parasol monoplane showing the usual Nieuport highly-finished metal skin application. The engine is a Hispano 12 Nb. unsupercharged and direct drive. One of the most remarkable aircraft in the show is the Nieuport-Delage 590, which is of the class now described as " Colonial." It is a three-engined all-metal monoplane with 300 Lorraine engines. The fuselage " begins life " in front as an ordinary rectangular box, but a short AIR-COOLED PASSENGERS : The Nieuport-Delags 590 " Colonial " monoplane has an open " balcony " which gives the machine gunners a free field and at the same time protects them from the slipstream. 1110
